The battery was charged with a battery
charger or jump started.

Have the battery checked at a service
station.
The battery is no longer charging.
Possible causes:

alternator malfunctioning


broken poly-V-belt
Do not forget that the brake system re-
quires electrical energy and may be oper-
ating with restricted capability.
Considerably greater brake pedal force is
required and the stopping distance is in-
creased.

Stop immediately in a safe location or
as soon as it is safe to do so and
check the poly-V-belt.
If it is broken:

Do not continue to drive. Otherwise
the engine will overheat due to an in-
operative water pump which may re-
sult in damage to the engine. Notify
an authorized Mercedes-Benz Center.
If it is intact:

Drive immediately to the nearest
authorized Mercedes-Benz Center.
Adjust driving to be consistent with
reduced braking responsiveness.

quires electrical energy and therefore has
only limited operation. Considerably
greater brake pedal force is required and
the stopping distance is increased.

Stop the vehicle in a safe location as
soon as it is safe to do so. Adjust driv-
ing to be consistent with reduced
braking responsiveness.

Notify an authorized Mercedes-Benz
Center.

The electrohydraulic brake system is in
emergency operation mode. Consider-
ably greater brake pedal force is required
and the stopping distance is increased.
The maximum speed is limited to 55 mph
(90 km/h).

Do not drive any further.

Stop the vehicle in a safe location as
soon as it is safe to do so and notify
an authorized Mercedes-Benz Center.

Prevent the vehicle from rolling away
by blocking the wheels with wheel
chocks or other sizable objects.
